Name of product or service:
Global Ecosystems Database
Data set available at: http://www.ngdc.noaa.gov/ecosys/ecosys.shtml
Type of change:
Discontinue archival support and data distribution at NGDC.
Description:
The Global Ecosystems Database (GED) project began in 1990 as an Interagency project between the National Geophysical Data Center (NGDC) of the U.S. National Oceanic and Atmospheric Administration (NOAA), and the U.S. Environmental Protection Agency's (EPA) Environmental Research Laboratory in Corvallis, Oregon (ERL-C). The primary objective of the project was to produce a spatially integrated database (including observational time sequences and model simulation outputs) with high quality metadata for characterization and modeling support within the US Global Change Research Program (USGCRP). Datasets were selected for publication to meet research priorities established by the EPA/ERL-C and to expand the use of datasets of potential value to the modeling and applied research community.

Following prototype development, the first publicly released volume of the database was GED "Disk A" (September 1992). In 1993 datasets for Disk B were distributed for review. The final version of disk B, published in 1997 completed the review, update, and publication process with new or revised versions plus several important additional datasets contributed through 1997.  The current online GED combines the datasets from Disk A and Disk B, the former has been updated from its original version to meet the same metadata standards as Disk B. 

NGDC no longer has data stewardship support or a mission focus to continue supporting this data set.  The lead author, Dr. John J. Kineman, Senior Research Scientist at the University of Colorado (http://cires.colorado.edu/science/groups/wessman/people/kineman/) will maintain a complete set of the data.  Future possibilities include a data transfer to the National Climatic Data Center.

Current Notice of Proposed Changes (2)

Last Updated:

Name of product or service:
NESDIS GOES 5x5 Sounding BUFR Retrievals
Type of change:
Replacement / Retirement
Description:
The replacement GOES 1x1Sounding BUFR Retrievals product will begin transmission to the user on November 22nd at 15Z UTC. The GOES 5x5 Sounding Retrievals are vertical atmospheric temperature or moisture profiles derived from radiances measurements. The radiance measurements are from a variety of instruments flown on NESDIS’ current GOES EAST/WEST weather satellites. The GOES 5x5 bufr sounding retrievals are being generated twice per hour per satellite. All of the retrievals are placed into BUFR format to be utilized by users. The profiles are averaged over a 5x5 pixel area giving a resolution of 50 km. The new and improved 1x1 bufr sounding retrievals that have replaced the 5x5 are at 10 km resolution and give profile information for each pixel. This improvement equates to about .4 mm for Precipitable Water (PW) and about .3o – .5o K for temperature. The increase in the amount of data being produced and transmitted to the users per hour, allows for more overall detailed analytical information.
